Consulting: Pulp and Paper

Spectrum-Tec has provided services to various industries, including pulp and paper, steel, mining, petro-chemical, automotive, and water purification.

 

Spectrum-Tec diagnoses and resolves vibration concerns on large-scale rotary and oscillating equipment for pulp-and-paper manufacture, improving productivity and minimizing risk.

 

The following is a partial list of problems that Spectrum-Tec has resolved in the pulp-and-paper industry:

• measuring variability of paper
• making mill measurements to determine the source of paper variability and fix the problem components
• performing operating deflection shape analysis and modal analysis to characterize the vibration of a paper machine headbox
• performing wet end audits of the paper machine
• building a finite element model of a headbox to review the support structure
• modal testing of a TMP refiner to characterize its modal (vibrational) properties
• operating deflection shape analysis and modal analysis of a refiner tank rotor
• finite element modeling of calender rolls to determine the effects of thermally induced distortion
• providing recommendations to optimize the roll and or reel operation
• thermal analysis of a super critical water oxidation reaction process
• utilizing modeling and measurement skills to determine sources of vibration from winding roll of paper
• leading edge research on calender barring, a type of self-excited vibration
• development of instrumentation used to increase productivity and quality in a paper mill
